  • Weird buzzer situation

    Haven't had a chance to look into the rigging manuals like I need to yet, but just throwing this out there.

    Old, 1997ish proline boat was just completely redone, and whoever did it spared hardly any expense. twin OX66 engines, 1999 and 2000 I believe. Motors were gone through and rebuilt I think.

    Has the twin 704 binnacle and key switch assembly.

    Turn the key to on, and the buzzers chirp like they should. But after the few seconds of them giving the test sound to let you know they are working, the noise level drops off but still buzzes. Its really quiet, some people can hear it, some can't. Its not like the normal volume level. Open the console and if you literally just touch the buzzer, it suddenly stops. When I was working on it, it was just the starboard buzzer doing it. I put a new buzzer on there and it fixed the problem...for the starboard side. (Although now that buzzer doesn't give the test alarm when you first turn the key on?)

    Well, about a month later, and now the port side buzzer is doing the exact same thing now. Stops buzzing as soon as you just simply touch it. I'm guessing some kind of electrical interference? What do you think?

    Yamaha or something they found elsewhere?

    I read somewhere before hat the old radio shack buzzers cause problems

      Not twins with a 703 box but sounds something like this.

      Were new buzzers installed? Sounds like some residual ground remains in the ECU.

        Interesting boscoe.


        It had the old style, and my replacement I think was the new style. I don't remember if grey sleeve or not, but I remember it had red stripes on the wires like in that picture. It's still odd though that they did not buzz when they have the key on power.

          I may be wrong, but I thought single motor set ups do not buzz at key on but duel motor set ups do.

          I have no idea how they make the duel set up buzz at key on.

          always thought it was to let the operator know that one motor died.
